What is the difference between MAC address IP Address and port address?
The main difference between MAC and IP address is that MAC Address is used to ensure the physical address of the computer. It uniquely identifies the devices on a network. While IP addresses are used to uniquely identifies the connection of the network with that device takes part in a network. 1.
What differences have you observed between your MAC and IP Address?
MAC Address and IP Address
| MAC Address | IP Address |
|---|---|
| Mac address is separated by colons. | Ip address is separated by dots. |
| Mac address is hardware oriented. | IP address is software oriented. |
| You can’t hide the mac address from the device. | It is possible to hide IP addresses using the router or VPN. |
Why do we have MAC address IP Address and also port numbers can’t we communicate with only one address?
Computer A could potentially learn the IP Address of Computer 2. And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
Is there any relation between the MAC address and IP Address of a host?
There is no relationship. A MAC Address is a layer-2 address, and an IP address is a layer-3 address. The network layers are independent of each other. A MAC address can have different layer-3 protocols with different layer-3 addresses.
What is the difference between the MAC address and IP address which layer of the OSI model does each operate at?
Implementation Layer: The IP address or logical addressing is implemented in the Network layer of the OSI or TCP/IP model. On the other hand, the MAC address or physical addressing is implemented in the Data-Link layer of the OSI or TCP/IP reference model.
Are MAC addresses unique to each device?
In the OSI reference model for networking, the MAC is a Layer 2 — or data link layer — device, and the MAC address is a Layer 2 address. Each MAC address is unique to the network card installed on a device, but the number of device-identifying bits is limited, which means manufacturers do reuse them.
Why do some devices have the same MAC address?
Duplicate MAC Addresses In order for a network device to be able to communicate, the MAC Address it is using must be unique. No other device on that local network subnet can use that MAC Address.
Are all MAC addresses different?
A MAC address is NOT unique for every computer. Manufacturers do indeed try to pick MAC addresses for their cards which are globally unique, BUT: MAC addresses can be overridden in software. Your computer doesn’t have to use the default MAC address of a given network card.
